You can use the Procedure Editor (see “Using the JavaScript Procedure Editor

The attributes displayed after opening the Data Calculator window in the
Tabular view are related to attribute structure of the IN-port and the OUT-Port.
You can also add additional transformation rules. This is extremely helpful if
the number of OUT attributes does not match the number of IN attributes, or if
additional attributes have been added to the project at a later stage of
development.
Note The view in the Graph Tab mirrors the actual Port Structures. You cannot
add or delete attributes there.
❖ To manually add transformation rules
1 Right-click anywhere in the Transformation Rule and Current Output Port
column.
